<Fig. 1> Boom box / Cassette deck
<Handling cassette tapes>
Cassette tape suitable for recording:
The X-12 is designed to perform best with
high-position cassette tape (TYPE II, HIGH).
We recommended these or their
equivalent.
The tape in C-120 versions (60 minutes
each side) is too thin and not suitable for
repeated recording or playback. Use C-90
or shorter tapes for stable performance.
Using write-protection tabs:
On the spine of a cassette tape are write-
protection tabs that are used to prevent
any recorded data from being erased
accidentally.
You may want to break the tab for side A
and side B of a cassette tape that you have
already recorded, since the X-12 uses all
four tracks at the same time.
If you later wish to record data on a tape
with broken tabs, apply a piece of scotch
tape to cover the tab hole.
Hint!
You can perform multitrack recording
using a tape that was recorded on a boom
box or a cassette deck. Refer to page 16
for more details.
<Fig. 2> Multitracker, such as X-12
<Differences between multitracker and
cassette deck recording>
Boom boxes and stereo cassette decks
record on both the A and B sides of cassette
tape. As shown in Fig. 1, the cassette tape
is divided in 4 tracks of which 2 are used
for the A side and the remaining 2 for the
B side (4 track 2 channel).

A multi-tracker as shown in Fig. 2, all four
tracks can be recorded without turning
over the cassette (four track 4 channel).
For the X-12, the 4 tracks are recorded
one at a time (some multitrackers can
record multiple number of tracks in each
pass). Also, in multitrackers, since all
tracks are recorded in the same direction,
if such a cassette tape is played back in a
radio cassette or cassette deck, tracks 1
and 2 will be heard correctly but if the
tape is turned over, tracks 3 and 4 will be
heard in reverse.
Write-protection tabs
** Advice **
Fresh or recorded tapes should not be
kept in locations of strong magnetic
fields (near speakers and TV sets) and
stored in dust free and non-humid
locations.
Before Using the X-12

2. Do not directly apply an output signal from the [LINE OUT] jack to the [INPUT] jack.
As shown in schematic below, if the [LINE OUT] jack is directly connected to the [INPUT] jack
and the [LINE OUT/PHONES] knob is raised, it will cause oscillation. Should you be monitoring
by headphone, this could hurt your hearing.
1. Do not bring the microphone too close to the monitor speakers connected to the [LINE OUT]
jack when the [LINE OUT/PHONES] level control knob is raised.
Doing so could cause feedback from the speaker and headphone which could damage your
hearing.

Model X-12 Owner's Manual
The X-12 uses the following connection plugs:
Stereo phone plug (stereo type)
Use this plug to connect to the [PHONES] jack.
< Gain control rule of thumb >
The gain is adjusted by rotating the [LINE-MIC]
knob while watching the lighting condition of
the level meter LED as the signal is input.
Gain of "MIC" is obtained at full CW rotation of
the [LINE-MIC] knob and "LINE" at full CCW
rotation.
Ideal gain is obtained by setting the level meter
reading such that the "+6" LED does not light
up. Should the "+6" LED lights up frequently,
it is an indication that gain is too high and will
result in distortion if recording is continued in
this manner.
Basically, the knob should be adjusted toward
"MIC" when a low level sound source such as a
mic is connected, and toward "LINE" when
connecting the output of an effects unit to which
a keyboard or electric base is connected.

Model X-12 Owner's Manual
Connect the AC adaptor jack to the X-12's [DC
IN] connector, and connect the power plug to
the AC outlet.
Basic Operation (recording)
As explained above, there are four recordable tracks.
The X-12, records each track independently. Let's try recording your mic/guitar/
keyboard on the track of your choice. As an example here, the mic sound will be
recorded in track 1.
Press the [PLAY] button to forward the tape for
a few seconds.
This should be performed in order to wind
past the leader part at the beginning of the

When the leader part is forwarded, press
the [RESET] button to set the counter to
"000."
Select the track to be recorded with the [REC
TRACK] selector.
Select track 1 (the indicator will change to
red) or whatever track you prefer to record
on.
Try speaking into the mic.
The level meter LED will blink.
Put X-12 in the record standby mode.
First, press the [PAUSE] button, then the
[RECORD] button. The [PLAY] button will be
engaged automatically at the same time.
The tape will remain paused in the record
mode.
When the [LINE OUT/PHONES] knob is
slowly advanced, the input monitor sound
will be heard in the headphone.
While monitoring the sound in the
headphone, watch the level meter and adjust
the recording to a suitable level.
Because the recording level cannot be
adjusted with a fader, optimum recording
levels must be determined by the sound
volume applied to the mic or by adjusting
the distance to the mic.
<CAUTION>
If you must monitor for a long time, be
careful not to raise the
[LINE OUT/PHONES]
knob too high. If you monitor for long
hours at high volumes, it could impair
your hearing.
After confirming the level, release the
[PAUSE] button (The [PAUSE] button is
pressed again) to start recording.
If recording is to be momentarily stopped,
press the [PAUSE] button. If recording is to
be ended, press the [STOP] button.
Following the procedures up to this point,
the sound applied to the microphone has
been recorded on track 1 as shown in
schematic below.
Now, let's try recording another sound source
to another track with the same procedures.
Also, lets playback the recorded sound on
each track as described below.
<NOTE>
Be careful not to continue recording, if
the level meter
"+6"
LED lights up
frequently, as this will indicate the sound
can be distorted.
For optimum gain, adjust the [LINE-MIC]
knob CW (toward "MIC").
Adjust the [LINE-MIC] knob such that the level
meter "+3" LED is illuminated at maximum
sound volume.
When recording line level sound sources such
as a keyboard and electric guitar, the
optimum gain is obtained by rotating the
[LINE-MIC] knob CCW (toward "LINE").

Advanced Operation
At this point, we assumed that you understand recording and playback of each track after
studying the [Basic Operation] section and are ready to move on.
Next up, we'll work on more advanced functions such as multitrack recording - called
"overdubbing" - which is fundamental in multiple recording, then the mixdown process when
sounds recorded to the four tracks will be mixed to stereo, and finally, copying (dubbing) of the
mix to a master recorder (stereo cassette deck, etc.).
1. Overdubbing
Overdubbing is a recording technique used to add a recorded performance to previously recorded
tracks while listening (monitoring) to them.
For example, you might record a rhythm section (such as a drum machine) on Track 1 by
following the basic recording procedure, then record an electric bass on Track 2 while listening
to the recorded rhythm. In this way, you can record performances on all four tracks, one by
one. This section uses an example in which Track 1 has the drum machine already recorded.
Follow the recording steps described in the Basic Operation chapter and use the drum machine
instead of the microphone. We are going to overdub the electric bass on Track 2, the keyboard
on Track 3, and vocal on Track 4.
While playing back and listening to Track 1 (drum
machine), overdub the electric bass to Track 2.
While playing back and listening to Track 1 (drum
machine) and Track 2 (electric bass), overdub
the keyboard to Track 3.
While playing back and listening to Track 1,
Track 2 and Track 3, overdub the vocal to Track
4.
Step-1 Step-2
Step-3

Model X-12 Owner's Manual
Before you start overdubbing, practice your electric bass performance while monitoring the
drum machine recording in Track 1 through the headphones.
After you finish recording, press the [STOP]
button or the [PAUSE] button to stop the tape.
If you have pressed the [PAUSE] button, press
the [STOP] button to release the [REC] button
and [PLAY] button, then press the [PAUSE]
button again.
After you set the recording level, playback
the tape from the "000" point and rehearse
your bass accompanying the drum machine
recording on Track 1.
Use playback level fader 1 and the playback
[PAN] knob 1 to adjust the monitoring level
and balance of Track 1.
Insert the tape on which the drum machine
has already been recorded, and rewind the
tape to the recording start position "000."
The output of the effects unit to which the
electric bass is connected is plugged into
the [INPUT] jack.
Adjust the recording level of the electric bass.
Play the electric bass to check to see how the
level meter is responding. (Use the output
volume on the bass so that the level is not
too high.) Use the [LINE OUT/PHONES] knob
to adjust the headphone volume to an
appropriate level.
After you finish rehearsing, rewind the tape
to the "000" point.
Using the [REC TRACK] selector, select track
2 for recording.
Press the [PAUSE] button, the press the [REC]
button.
The X-12 will enter record pause mode.
Press the [PAUSE] button again to cancel record
pause mode and start recording.

2. Mixdown
Mixdown is a technique that enables you to adjust the volume balance of the
overdubbed tracks 1-4, combine them to two channels, and dub (copy) to a master
recorder (cassette deck or MD recorder etc.). Refer to the diagram below:
Adjust the output level and balance (pan
position) of tracks, then adjust input level
on the master recorder.
Insert a tape with tracks 1-4 already recorded
into the cassette tray, and rewind the tape
up to the playback start point (reset the
counter to "000").
Connect the input jack of a master recorder,
such as cassette deck, and the [LINE OUT
L, R] jacks.
Insert a recording tape (or MD) in the master
recorder and locate the point on the tape at
which you wish to start copying.
Set the master recorder to the record standby
mode. (That is, press the [PAUSE] button so
that the level meter will respond, then set the
recorder in record pause mode.)
The method for setting the recorder in record
standby mode will vary depending on the
recorder you are using.
Refer to the instruction manual of the master
recorder for more information.

Model X-12 Owner's Manual
<Note>
You can position the sound on tracks 1-4 anywhere in stereo image on
mixdown.
This is where your creatively is important. Try for a sound that is pleasing
to you!
You can record your favorite music on a boom box or cassette deck and overdub your
performance or vocal, accompanying your musician's performance to make your own
original tape. Follow the procedure below to make this type of tape.
Track 4
Track 3
Track 2 (R channel)
Track 1 (L channel)
Record your favorite song to Tracks 1 and 2 on the
boom box or cassette deck.
Do not record now. Later, you will record your
performance or vocal here on the X-12.
2. Insert the recorded tape in the X-12, and follow the "Overdubbing"
procedure described previously to record your performance or vocal
to Tracks 3 and 4.
<NOTE>
Note that the law prohibits recording copyrighted or broadcast music, except for
recordings intended only for personal use.
After finishing the level adjustments, rewind
the tape to the "000" point.
Now you can begin mixdown.
First start recording on the master recorder,
then press the [PLAY] button on the X-12 to
start playback.
After mixdown is complete, stop the X-12 and
the master recorder.
Play back the tape on the X-12.
While monitoring the sound via the headphones,
use the playback fader and the playback [PAN]
knob of each track to adjust the output level
and balance of the tracks.
Gradually raise the headphone volume using
the [LINE OUT/PHONES] knob. This knob also
adjusts the output level at the X-12's [LINE OUT
L, R] jacks. Set the level so that the level meter
of the master recorder will respond moderately.
<NOTE>
Be sure to record on only one side of the tape (side A or B).
That is, use Track 1 and 2 to record on the jam box or the cassette deck, and keep
Tracks 3 and 4 empty. (See the diagram below.)

Are you using a type of tape other than high
position?
Use a high-position tape.
Is the level appropriate for the input signal?
Use the [LINE-MIC] knob to set the optimum
level.
Place a strip of scotch tape over the broken
tab.
Is the write-protection tab on the cassette
tape broken?
Turn the [LINE OUT/PHONES] knob.
Is the [LINE OUT/PHONES] knob turned
up?
Set the [REC TRACK] selector repeatedly
until the desired track is selected.
Is the [REC TRACK] selector set correctly?
Symptom
Maintenance
* Cleaning the exterior
For normal cleaning, use a dry cloth.
For stubborn dirt, moisten a cloth in diluted
detergent, wring it out firmly, and wipe the dirt
off. Then polish with a dry cloth.
Never use solvents such as alcohol, thinner or
benzene, since these will damage the printing
and finish of the exterior.
* Cleaning the head
As the X-12 is used, the record/playback head
will become coated with oxide residue from the
tapes. If this residue is allowed to build up,
recordings will contain more noise, and
dropouts may occur during playback.
To prevent this, regular cleaning is important.
Use a commercially available cleaning kit etc.
to clean the head. If cleaning the head does
not restore the sound quality, it is possible that
the head is worn. Contact an authorized Fostex
service station for repair.
* Cleaning the pinch roller and capstan
The capstan and pinch roller are important
parts that hold the tape and move it along at
the correct speed. As with the head, these parts
can also become dirty with oxide residue and
dust, which will cause increased wow or flutter,
or even damage the tape by pulling it out of
the cassette. Since cassette tape is very thin, it
is especially dangerous to use a cassette deck
with dirty pinch rollers. As with the head, it is
important to always keep these parts clean.
Clean them using a cotton swab or gauze soaked
in cleaning solution or isopropyl alcohol. Never
use organic solvents such as lacquer thinner,
since this will severely damage the pinch rollers.
* Demagnetizing the head
After long periods of use, the head begins to
develop a magnetic field in addition to the oxide
residue described above. This can also occur if
a magnet or a magnetized object (scissors, etc.)
is allowed to come near the head or touch it. If
the head or capstans become magnetized,
frequency response will be degraded and noise
will increase.
In extreme cases, noise can be created on
previously recorded tapes that you playback,
rendering them useless. Once a month or so,
you should use a demagnetizer (head eraser)
to demagnetize the head. Carefully read and
follow the instructions included with your
demagnetizer, and do not allow it to come near
recorded tapes.
Is the AC adaptor plugged in securely?
Sound flutters or skips.
The sound distorted or
clipping.
The [REC] button is not
pushed in.
The sound cannot be heard
through the headphones.
You cannot record to a
desired track.
